# ImGUI runtime inspector
`igri` is a runtime inspector powered by [imgui-rs]
[imgui-rs]: https://github.com/imgui-rs/imgui-rs
```rust
use igri::Inspect;
#[derive(Inspect)]
pub struct MyCoolStruct<T> {
xs: Vec<T>,
}
```
## `dummy` feature
We want to disable developer UI on release build. Enable `dummy` feature flag to turn off `#[derive(Inspect)]` expansion.
> Be sure to out put other calls to `igri`, too!
